Has anyone experienced this? Several days ago my young African goose started limping. I thought maybe she just hurt her leg somehow, she's very clumsy. Yesterday I noticed her neck was very swollen. It feels like it's full of air bubbles. She has good appetite but is a little more lethargic than normal, but I'm thinking it's because her leg hurts and she doesn't want to walk as much. Today I notice that several of my ducks have also developed swollen neck, but otherwise appear fine. I can't find any helpfull info on the internet, so if anyone has any ideas of what this might be, I'd sure appreciate any help.
